According to the kit disclosed by the invention, the ratios of the latex particles with different particle sizes are strictly defined, so that the sensitivity and the specificity of detection are improved; therefore, a surfactant and stabilizing agent combination suitable for the system is obtained; on the premise of high measurement speed and sensitivity and high specificity, the whole system is high in stability and easy and convenient to operate, and is suitable for being matched with a clinically full-automatic or semi-automatic biochemical analyzer in use.
